摘　　要：以豹子沟煤业10109工作面为研究对象,采用高密度三维电法对工作面顶板灰岩地层富水性进行采前探测。根据探测结果,结合现场煤层起伏构造变化情况,在工作面运输巷自切眼向外布设4个顶板水疏放钻孔,有效地解决了工作面顶板K2灰岩岩溶裂隙水害的威胁,保障了豹子沟煤业10109工作面安全开采。Taking the 10109 working face of Baozigou Coal Industry as the object,the high-density three-dimensional electrical method is used to detect the water abundance of the limestone strata on the roof of the working face before mining.According to the detection results and in combination with the change of the undulating structure of the coal seam at the site,four roof water drainage boreholes are arranged outward from the cut hole in the haulage roadway of the working face,which effectively solves the threat of water damage in the K2 limestone karst fissure water of the working face roof,and ensures the safe mining of the 10109 working face of Baozigou coal industry.
